Abstract

Bloc optique (1) de véhicule comprenant, un boîtier (2) avec une vitre, une lampe (3) disposée dans un réflecteur (4) concave réfléchissant la lumière produite par la lampe (3), le réflecteur (4) comportant un bord extérieur (40), le bloc optique (1) comprend une LED (10) fixée sur une carte électronique (5), la LED (10) et la carte électronique (5) étant disposés à l’extérieure du réflecteur (4) et dans le bloc optique (1). Le bloc optique (1) comporte une paroi écran (6) s’étendant depuis une partie du bord extérieur du réflecteur (4) vers la vitre, le long du bord extérieur (40) situé entre le réflecteur (4) et la carte électronique (5) de sorte à empêcher l’air chauffé par la lampe (3) de se déplacer directement vers une partie de la carte électronique (5) en sortant du réflecteur (4), de préférence la partie de la carte électronique comportant la LED (10). Figure pour l’abrégé : Figure 2Vehicle optical unit (1) comprising, a housing (2) with a window, a lamp (3) arranged in a concave reflector (4) reflecting the light produced by the lamp (3), the reflector (4) comprising an edge outside (40), the optical unit (1) comprises an LED (10) fixed on an electronic card (5), the LED (10) and the electronic card (5) being arranged outside the reflector (4) and in the optical unit (1). The optical block (1) comprises a screen wall (6) extending from a part of the outer edge of the reflector (4) towards the glass, along the outer edge (40) located between the reflector (4) and the electronic card (5) so as to prevent the air heated by the lamp (3) from moving directly towards a part of the electronic card (5) leaving the reflector (4), preferably the part of the electronic card comprising the LED (10).
